Dc high voltage generator common failure and solution

Dc hi-pot generator in the use of the process may have some failures, the following are some common failures and treatment methods:

After the power switch is turned on, the power indicator and green light are not on. This may be due to a problem with the power fuse, power cord, or power switch. The solution is to inspect these parts, and if any of them are found to be damaged, they should be replaced promptly。

After turning on the power switch, the power indicator flashes green and is accompanied by a buzzer, which may be because there is no grounding, unreliable grounding or used generator power, or power that passes through the switchgear isolation transformer. The solution is to perform grounding operations, check whether the grounding cable is reliable, and re-ground if necessary. If the power supply has been isolated or spontaneous power supply used in the field, it must be artificially connected to the ground.

Sometimes it may be encountered that after opening the power switch of the DC high voltage generator, the power indicator is green, but the high voltage indicator is red (that is, the high voltage cannot be closed).This may be caused by the voltage regulator potentiometer not being in zero position, the overvoltage setting switch being set to zero, or the high voltage indicator button light may be damaged.The solution is to turn the potentiometer back to zero, make sure the overvoltage setting switch is set correctly, and check that the high voltage indicator button light is working properly.

Another common fault is that when the power switch is turned on, the digital display meter on the control box does not show. This is usually due to a problem with the power connection or fuse. This problem can be solved by checking the power connection and all the fuse. If the fuse is found to be damaged, a new fuse should be replaced according to the amperage marked next to the fuse seat.
